Chicago to Allentown/Bethlehem/Easton

What the Data Says About ORD to ABE

The Chicago to Allentown/Bethlehem/Easton corridor (ORD → ABE) covers roughly 654 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 2,317 flights in the dataset, this route posts a 80.2% on-time rate with an average delay of 78.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,421 flights were recorded on this pairing — 27 cancelled (1.9%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,317 total flights analyzed, the 80.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.5-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Oct 2022 posted the best performance on this corridor at 94% on-time, while Jul 2023 came in at 55% on-time — a 40-point gap between best and worst recent month. For travelers evaluating the ORD to ABE route, the combination of a 80.2% on-time rate, 78.5-minute average delay, 1.9% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
